Also still on X11 because of xorgxrdp and X11 forwarding.

It would be cool to see this test with a CRT connected to a VGA port (adapters make it slower) and a PS/2 input device.

I have been having great luck with waypipe (gitlab) as an X11 forwarding alternative (OS X to Ubuntu 24.04). The setup was relatively painless and it 'just worked.' while this might not suit your needs for other reasons I was pleasantly surprised.
